Who is more respectful, 1) The guy who is honest, even when it offends some women? 2) The guy who hides his true opinion in order to 'have a quality relationship'?
If his opinion is not respectful, neither of these hypothetical men are respectful or respectable. Sexist assholes are sexist assholes, whether or not they conceal their sexism.
That said, the purported "research" is gibberish, and I hope it is satire in and of itself. If it's not, then it deserves at least some gentle mockery. I don't know if "C Plus Equality" does that well, or if it's just juvenile dick jokes, but a self-publishing platform (which is what Github boils down to) shouldn't be in the business of making value judgments.
